Summary

NT5C2 (5’-nucleotidase, cytosolic II, HGNC:8022) is a protein-coding gene on chromosome 10q24.32-q24.33, encoding Cytosolic purine 5’-nucleotidase (P49902). Broad specificity cytosolic 5’-nucleotidase that catalyzes the dephosphorylation of 6-hydroxypurine nucleoside 5’-monophosphates. In precision oncology, NT5C2 R367Q is associated with resistance to Mercaptopurine + Thioguanine in Childhood Acute Lymphocytic Leukemia (CIViC Level C); 12 further curated variant–drug associations are listed below.

This gene encodes a hydrolase that serves as an important role in cellular purine metabolism by acting primarily on inosine 5’-monophosphate and other purine nucleotides.

UniProt curated annotations — full annotation on UniProt →

Function. Broad specificity cytosolic 5’-nucleotidase that catalyzes the dephosphorylation of 6-hydroxypurine nucleoside 5’-monophosphates. In addition, possesses a phosphotransferase activity by which it can transfer a phosphate from a donor nucleoside monophosphate to an acceptor nucleoside, preferably inosine, deoxyinosine and guanosine. Has the highest activities for IMP and GMP followed by dIMP, dGMP and XMP. Could also catalyze the transfer of phosphates from pyrimidine monophosphates but with lower efficiency. Through these activities regulates the purine nucleoside/nucleotide pools within the cell.

Subunit / interactions. Homotetramer.

Subcellular location. Cytoplasm. Cytosol.

Tissue specificity. Widely expressed.

Disease relevance. Spastic paraplegia 45, autosomal recessive (SPG45) [MIM:613162] A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. Some SPG45 patients manifest intellectual disability, contractures and learning disability. The disease is caused by variants affecting the gene represented in this entry.

Activity regulation. Allosterically activated by various compounds including ATP, 2,3-BPG/2,3-Bisphosphoglyceric acid and Ap4A/P1,P4-bis(5’-adenosyl) tetraphosphate. Binding of an allosteric activator is a prerequisiste to magnesium and substrate binding. Inhibited by inorganic phosphate.

Cofactor. Binds 1 Mg(2+) ion per subunit.

Similarity. Belongs to the 5’(3’)-deoxyribonucleotidase family.
